Black and odorous water treatment equipment

summary:

With the acceleration of urban-rural integration in China, rapid economic and construction development, and population growth, the discharge of black and odorous water has also increased sharply.Zhongqiao Environment has developed and launched the "Black and Stinky Water Integrated Sewage Treatment Equipment" based on the characteristics of black and odorous water. On the basis of the original integrated sewage treatment equipment, it has been fully upgraded to an "Intelligent Management System". The electronic control system has added 4G transmission, enabling users to remotely control and view the sewage treatment system from any corner of the world. The free wireless network card is also very practical. Especially suitable for projects, practical use in various food factories, and truly high-end equipment. Enhance the brand image of your enterprise!

Equipment name: Black and odorous water treatment equipment

Main material: Carbon steel

Application scope: Purification and treatment of black and odorous water bodies

Black and odorous water integrated sewage treatment equipment diagram

The characteristics of black and odorous water treatment equipment are as follows:

(1) Point source pollution and non-point source pollution coexist, while domestic pollution and industrial pollution overlap;

Multiple sources: In addition to human feces and kitchen wastewater, there are also wastewater generated from household cleaning and the infiltration of household waste;

(2) Various types of old and new pollution are intertwined;

Rapid growth: With the improvement of farmers' living standards and changes in their lifestyles, the amount of domestic sewage generated has also increased;

(3) Transfer of industrial and urban pollution;

(4) The environmental protection policies, regulations, and standard system are not sound.

(5) The concentration of nitrogen and phosphorus in sewage is high, and it contains a large amount of nutrients, bacteria, and viruses.


Therefore, it is urgent to accelerate the treatment of black and odorous wastewater, effectively control the black and odorous water bodies, and improve the living environment of residents.

Black and odorous water treatment equipmentDesign principles and processes

1. The integrated sewage treatment equipment for black and odorous water is buried below the surface, and the surface above the equipment can be used for greening or other purposes without the need for building houses, heating, or insulation.

2. The secondary biological contact oxidation treatment process adopts push flow biological contact oxidation, which has a better treatment effect than mixed or two-stage series mixed biological contact oxidation tanks. And it has a smaller volume than activated sludge tanks, strong adaptability to water quality, good shock load resistance, stable effluent quality, and will not cause sludge expansion. A new type of elastic three-dimensional packing material is used in the pool, with a large specific surface area and easy biofilm formation and detachment by microorganisms. Under the same organic load conditions, it has a high removal rate of organic matter and can improve the solubility of oxygen in the air in water.

3. The biochemical tank adopts the biological contact oxidation method, which has a relatively low volume load of the filling material, and the microorganisms are in their own oxidation stage, resulting in low sludge production. It only takes more than three months (90 days) to discharge the sludge (using fecal trucks to suction or dehydrate into sludge cakes for external transportation).

4. The deodorization method of this buried domestic sewage treatment equipment not only uses conventional high-altitude exhaust, but also includes soil deodorization measures.

5. The entire equipment processing system is equipped with a fully automatic electrical control system and equipment fault alarm system, which operates safely and reliably. Generally, there is no need for dedicated personnel to manage it, and only timely maintenance and upkeep of the equipment is required.

Installation, use, and maintenance

1. Foundation: If the WSZ series equipment is placed above the floor, only a concrete floor with the same appearance as the equipment needs to be prepared as the foundation. The basic pressure must be greater than 4T/m²At the same time, it is also required to be level and flat.

If the equipment is buried below the floor, the foundation elevation must be less than or equal to the equipment elevation and ensure that there is no water accumulation during rain. The foundation is generally made of plain concrete (whether reinforcement is required depends on the local geological conditions).

2. Installation: Position according to the installation diagram, and place each box in sequence. The position and direction of the boxes must not be misplaced, and the spacing between them must be accurate, and the pipes must be connected properly.

2. Inject clean water into the equipment and check for any leaks in the pipes. If not, cover the area around the box with soil until the equipment inspection hole is reached, and level the ground. Connect the control line of the electrical control box to the water pump, and connect the electrical control box to the power supply. When wiring, pay attention to the direction of the fan and motor, which must be the same as the direction pointed by the fan.
